Seasonal Arena

Legend: Mothyards

Defend Vanguard forces with the Advanced Defensive Unit against an onslaught of 50 combatant waves.

Overview

Legend: Mothyards is the Legend-difficulty version of the Onslaught horde activity on the Mothyards map (Cosmodrome, Earth). Onslaught is a three-player activity added with the Into the Light content drop in Season of the Wish: Guardians defend an Advanced Defense Unit (ADU) against waves of Fallen and Hive enemies, then The Witness's forces. It is launched from the activity directory (the 50-wave version) rather than the 10-wave playlist version. It is currently active and has no announced sunset.

Difficulty and power

Legend starts at 1810 Power. One source says enemies begin 10 power levels above you and gain 5 per ten waves, comparable to a Grandmaster Nightfall; the Extinguish modifier is active from the start on Legend. Normal difficulty (1600 Power) only gets Extinguish after wave 30.

Encounters and mechanics

50 waves in five sets of ten. A boss wave closes each set, drawn from the Claw of the Witness, Fang of the Witness and Lightslayer variants.
Defend and repair the ADU. Earn Scrap from kills and spend it on turrets, decoys and tripmines at the start of each set and after the 3rd and 6th wave of a set.
Mandatory Augments must be completed or the team wipes; optional bonus objectives (zone capture, relic collection) give extra rewards.
A random Heatwave round can follow a boss kill, boosting ability regeneration and spawning Tormentors for extra Trophies of Bravery.
Map: Community consensus: Mothyards is a massive arena with no clear chokepoints. It is located in the Cosmodrome.
